It felt like calculated chaos inside the chilly convention center where Walmart had recreated one of its Supercenter stores. It was late August in Orlando, Fla., and the retailer had flown in thousands of workers to have a look. They were zipping around, trying to take it all in.

There were dozens of lit-up Christmas trees and poinsettias, rows of Halloween candy, and racks of knit dresses and sweaters. A Minnie Mouse mascot danced around the toy section, while wacky inflatable ghosts and foxes hovered above the inflatable jack-o’-lanterns in a pumpkin patch. Along the way, Walmart workers were chowing down on samples of pulled pork and chips, Oreo cookies and ice cream.

A candy cane door frame welcomed people to the North Pole — and into Walmart’s annual business meeting for the holiday shopping season.

On that sweltering day, the nation’s largest retailer was trying to set the mood for holidays that were still months off. But foremost on the agenda for the 6,700 attendees was Walmart’s slate of fall and winter events.

Beyond the festive mood, the holiday season is full of high stakes. It’s the busiest quarter of the year for most retailers, and Walmart’s preparations offer insights into consumer behavior and the state of the retail industry.
